This inventionrelates to a cutting-die used informing ornanientaledge portions on shoe-1 upper members, theV die including an'el'on-` gated knife and a holdertherefor from which 5 the cutting edge of the knife projects, the knife being formed to impart a predetermined contour to an edge of an upper member positioned on theknife vandfpressed against the cutting edge thereo f.` o

Usually the-die Aincludes also tubular cutting punches arranged in a row parallel with the knife, and adapted 'to cut a row of holes in theblank While thev knifeisforming a finished edge thereon. n f i i The chiefobject of the vide a die having means -ivhereby yit may be so adj ustedvthat the vcontour of the end portions of the cutting'edge'of'the knifeni'ayl be v'ariedto enable the die to formalinished edge, the end portions of Which may have either of a number ofdilferentl contours, so that a .sine` gle die maybe used informinglinished edges Y having differently contoured endportions.

means whereby the die maybe soadjusted that tliejcontour of the 'end portions ofthe cuttingedge of the 'knife,'and the'contouriof the ends of the row of punches, may besiL multaneously varied,;to enable the die to forma finishededge and aV row of holes, the. endv portions of Which may have eitherofa` number of different contours, all producible Vbya single die. y v l o Of the accompanying'v drawings forming a Vpart of this specification,;"

and are prevented from edgewise displacementV therein by pins 26 (Figure 9)entering longitudinal slots 27 (Figure 13) in the end edges" 18'LL (Figure 10) bearing on opposite 15 portions. i

I. Each pivoted section 19 is preferably provided with a flange 190 (Figure 4;), which is overhung by a holding-down flange on the A body section, as indicated by Figure -1.

lpo permit the simultaneous adjustment of the pivoted sections and positively confine them inA any position to which they may be adjusted, I provide adjusting means, prefer-` ably embodied in cylindrical studs 28, fitted to turn in sockets in adjacent swinging 'ends ofthepivoted sections, a nut 30 having oppositely projecting arms 31, .which are slidable inthe `studs 28, and an adjusting rod journaled in fixed bearings 32 and 33 (Figure 11), rod lhaving a lscrew-threaded portion 3a, engaged with the nut 30, and a knob for handle 35, whereby it.` may be rotated.

The upper member 17?, before it is acted on` bythe die has a surplus edge portion which an .bearsl on thecutting edge of the knife and ispositioned 'by spring-supportedV gage pins 3,6 (Fi ure 6'), someV of whicharelocated onl the bo yv section, and others on the pivoted sections. When the upper member is-thus o supported,L pressure is exerted `on it to cause the knife to remove the surplus edgev portion and thus form the finished edge portion Shown by vFigure 14. j. '1`heknifemay have al pinking cutting edge forming a pinkedv -inished edge'on the member 17.

vThe pivot-ed sections 19 may be provided with, rows of tubular punches 37a extending beside the slots-22 and forming continuations of a rowY of punches 37, vwith which the Y lat body sectionv 18 is provided.

f ,The usual springesupnorted stripper plate withA which adie of this'character is provided, toforcethemwork outward from the ated with the pivoted sectionsV and movable therevvitlif independently lof the plate secon; tions 38.` Each stripper plate or section may be secured t will noivbeseen that the ldescribed cut-Y il? knife and a knife-holder,having means for;V

lis ladapted to form a o studs 89, supported by springs" flexing the end portions lof the knife, is adapted to be adjusted to form on an article such as a vamp 17, an edge indicated by Fig- Vure'11, or an edge indicated by Figure 12,

each adjustment causing the cut edge to have a different contour at its end portion, so that a .single die maybe employed to produce finished edges Whose end portions have different contours.

The major or body portion l5 of the knife may be secured tothe body'section 18, by clamping it as indicated by FigureplO, be-

tween plates Vconstituting a fixed topV layer of the body section, andhaving knife-gripping v S0 sides of the knife. 'Ihe slots 22 1n the pivotedsections 19 receiving the end portions 16 yof the knife,are provided, in this instance,

by edges 18b (Figure 8) of the plates constituting fixed top layers of the pivoted sections. Each holder section mayinclude a hardened'steel plate 18c (Figures 8 and 10) lon which the knife and the tubular punches iear. Y

To simplify `the drawing, I have shown by Figure 1 only a portion of the stripper plate 38, the other stripper plates being omitted, all of `the stripper plates being shown by Figures 2 and 3. j

For V,the saine reason, I have omitted the J- strippenplates from Figure 11, and have shown said plates in Figures 8 and 12. There is,,of course, nothing nevv in the stripper plates, the plates or sections 38a being adaptations of a vvell known stripper plate elementto the pivoted knife-holder sections.

'Y It iso-bvious that the form of the knife,

and ofthe means securing the same` to the body section and the pivoted section, may be variously modified. The knife here shown 1;;

As shown by Figure 8, the pivot stud 21 isv tubular and its bore constitutes a portion of the Iclearance outlet'of one of the tubular punches `37, the borey of said punch being in alinement Withthe bore of thepivot stud.

The die may be adapted to kact on other shoe upper members, such as Wing tips, quarters, and .foxings It is to be understood'that my invention lli) .is not concerned with, parts shown by the major portion Vaf the knife, and a pair of piv-l` oted sections havlng means for confining the body section having means for confining' thev Amaj or portion of theknife, and a pair of pivoted sections having .means for confining the end portions of the knife, the pivoted sections being adjustable to flex saidend portions and thereby vary the contour of an edge cut bythe knife, the fixed and pivoted sec` tions being'provided with rows ofperforating punches arranged parallel with the knife,t

and adapted tovcooperate therewith in producing ornamentation of variable contour.
